Title: Improvements in or relating to colour photography
IPC: G03C7/00
Filed: 1920-04-12
Abstract: 141,699. Elmassian, P. April 11, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Colour photography. - In the interference method of colour photography, the radio-activity of the mercury, silver, or other radio-active material used in conjunction with the film is supplemented " instantaneously and simultaneously with the irruption of the rays reflected bv the object in the form of electricity, X-rays, light, or other form of free energy, so as to make up for the normal insufficiency of the radio-activity or these substances and by radiation in the opposite direction from these latter to aid, on the one hand, the extra rapid realization of the equilibrium of the stationary rays, the remainder of the available energy serving to effect the laminar formation of the different complementary colorations corresponding to the rays absorbed by the object. and on the other hand to aid in the prompt formation of the blacks by the process of superposition of unilateral rays in the region of the sensitive film where no ray comes from the object."

Abstract: 1374334 Cells with SO 2  electrolyte solvent AMERICAN CYANAMID CO 3 March 1972 10161/72 Heading H1B To prevent corrosion of the cathode electrode structure in cells having a non-aqueous electrolyte in which the solvent comprises sulphur dioxide, all the metal components of the structure in contact with the electrolyte consist of valve metal with a passivating surface film of the valve metal oxide. The film may be formed spontaneously when the cathode is placed in the electrolyte solution or it may be preformed by electrolytic treatment. The preferred valve metal is aluminium but alternative metals are tantalum, molybdenum, tungsten, niobium and alloys thereof. In an embodiment described the anode and cathode electrodes are of coiled strip form wound together with an intervening separator, the anode being on the outside of the coil. The cathode comprises a paper sheet of asbestos fibres and carbon particles supported on an aluminium expanded metal screen acting as current collector. The anode comprises a lithium foil supported on an expanded metal screen of copper. The coiled electrode assembly is placed in a steel can closed at one end by an aluminium disc insulated from the can. An aluminium tab connects the cathode to the disc and a copper tab connects the anode to the can. The can is filled with electrolyte comprising acetonitrile, propylene carbonate, lithium bromide and sulphur dioxide.

Patent GB-613068-A (GB)
Title: Improvements in and relating to dyeing fibres
IPC: D06B3/00
Filed: 1946-04-04
Abstract: Loosely piled fibres and fibrous materials are dyed at a temperature below the boiling temperature of the dyebath; and during the dyeing process bubbles of a gas which is noncondensible and non-soluble at the working temperature are introduced into the bath.  The materials are subjected to movement to dislodge <PICT:0613068/IV (c)/1> <PICT:0613068/IV (c)/2> adhering gas bubbles.  The gas, e.g. air, may be mixed with the dye liquor before its entry into the dyeing apparatus.  Apparatus is described (see Fig. 4) in which the material is placed between the two perforated plates 23 and 24 and dye liquor is circulated by the propeller 28 past the pipe 29 through which air is injected, through the plate 23, the material, and the plate 24, and back to the propeller through the perforated spiral pipe 25. At intervals the direction of flow of the liquid is reversed to dislodge adhering bubbles.  Apparatus is described also in which the goods are placed in a drum 31, Fig. 6, having perforated walls, ribs 40 and partitions 34, and which rotates in the dyebath 32.  Air is blown into pipe 38 and this injects dye liquor from the pipe 37 together with air bubbles into the drum 31, from which it returns to the injector through the pipe 37.  Other apparatus is described in which a fabric is passed in zig-zag fashion through a dyebath provided with a series of air injector nozzles along the bottom of the bath and a series of squeeze rollers above the level of the liquid.  Other apparatus is described in which a fabric is treated in piled condition and in endless length. Specification 436,875 is referred to.

IPC: G09B27/02
Abstract: 106,658. Wilson, W. May 29, 1916. Qu@eries.-In a tellurion designed to exhibit the motions of the sun, the earth, and the moon, an arm F<1> turning about a fixed support terminates in a bracket J, which carries a series of concentric tubes provided with pulleys L<2>, M<2>, K<5> driven by cords from fixed pulleys D, E<1>, G on a fixed support. An endless cord extends around a series of arms A<3> fixed to the base of the apparatus, and, passing up the inmost tube M<3>, rotates the pulley M<8>, from which motion is given to the earth. The uniform position of the earth's axis is maintained by rotation of the support M<4> mounted on the tube M<3> driven by the pulleys D, M<2>. The moon is carried on the vertical rod O<1> rigidly mounted on the support N, and is moved round the earth by the pulleys G, K<5>, the moon keeping the same face turned to the earth. Vertical motion is given to the moon by the arm P<1> rocked by the cam-plate L<3> on the tube L driven by the pulleys E<1>, L<2>. A shadow cap O<11> moves up and down with the moon, but is rotated independently, so as to show the surface illuminated by the sun, by a pulley O<6>, and another pulley which is mounted on a sleeve rigidly fixed to the bracket J. The sun is mounted on an inclined axis and is rotated by pulleys H, H<3>, H<4>, H<6> driving the tube I<4>, the end of which carries a pin I<5> engaging a slot in the sun. All the parts of the apparatus are driven by cords, which may be tightened by jockey-pulleys Q<3>, Q<4>, Q<5>. For accurate adjustment of the speed at which the parts are driven, the pulleys E<1>, G are split and their size varied by fine adjustment screws E'. Means are provided, such as the removable pin E<3>, for disconnecting parts of the apparatus, to show certain motions separately, and provision is made for exhibiting hypothetical motions such as the rotation of the earth on a vertical axis. The weights of parts carried on the arm F' is balanced by an arm F<2>, shown detached in dotted lines, which is made telescopic so that the balance can be adjusted. Eclipses can be demonstrated by the use of portable aluminium cones.
